SPECIFICATION forming part of Letters Patent No. 602,712, dated April19, 1898.

Application filed November 29, 1895. Serial No. 570,442. (No model.)

To aZZ whom it may concern.-

Be it known that I, J AOOB APPELL, a citizen of the United States, and aresident of Hilwaukee, in the county of Milwaukee and State ofWisconsin, have invented certain new and useful Improvements in Windows;and I do hereby declare that the following is a full, clear, and exactdescription thereof.

My invention has for its object to provide for the ready removal of sashfrom windowframes; and it consists in certain peculiarities ofconstruction and combination of parts hereinafter set forth withreference to the accompanying drawings and subsequently claimed.

In the drawings, Figure 1 represents a window-frame and sash embodyingmy improvements, the view being for the most part a longitudinal sectionon an irregular plane, with certain of the parts in elevation and brokenaway; Fig. 2, a front elevation with parts broken away, and Fig. 3 ahorizontal section on line 3 3 of the first figure.

Referring by letter to the drawings, A represents the stiles of awindow-frame provided with inwardly projecting sectional guidestrips 1)c for engagement with longitudinal grooves in the outer longitudinalfaces of sash-stiles B O, and the frame-stiles are also provided withvertical stops cl outside the sash. IVith the exception of the sectionalsash-guides and grooved stiles the frame and sash above specified arethe same in the matter of construction as those of common use,spring-catches 6 being shown as a means for holding said sash inadjusted position.

Each of the guide-strips b 0- comprises two sections, one of which ispermanently fastened to a stile of the window-frame, the other sectionbeing pivoted at one end to said stile. The meeting ends of theguide-strip sections are beveled to permit of the pivotal ones beingreadily swung away from the permanent ones when it is desirable toremove sash from the window-frame. The meeting ends of the sectionspertaining to each pair of guides are at such elevation as to requirethe bringing of each sash a greater distance than full length out ofnormal position before the movable sections of said guides can be swungon their pivots, and hence under ordinary'circumstances each guide ispractically rigid throughout to insure easy working of said sash and itsretention against displacement.

As a matter of detail it will be observed that the guides b have theirmovable sections pivoted to the upper ends of the frame-stiles, and theguides chave their movable sections pivoted to the lower ends of saidstiles.

In practice when it is desirable to remove the lower sash the latter isrun up 011 its guides 19 to clear the stationary sections of the same,after which it is swung out with the pivotal sections of said guides anddrawn therefrom, as will be best understood by reference to Fig. 1. Toremove the upper sash, it is run down on its guides to clear thepermanent sections of the same and then swung out with the pivotalsections of the latter guides to be drawn therefrom, this operationtaking place subsequent to the removal of the aforesaid lower sash.

It will be noticed that each inwardly-projecting guide-strip normallyextends from the top of the window-frame to the bottom of the same, andconsequently operates as a weatherstop the entire length of the sashwhen the latter is in closed position, this being a matter ofconsiderable importance in the practical application of my invention.

While the construction and arrangement of parts above specified does notincrease the cost of production in the matter of Windowframes and sash,it facilitates removal of the latter at any time such an operation maybe desirable and prevents marring of the woodwork in said frame andsash.

It is to be understood that while springcatches for holding the sash inadjusted position have been shown it is possible to employ weightedcords run on pulleys for the same purpose, as is common in the art towhich the invention relates.

Having now fully described my invention,

. what I claim as new,and desire to secure by Letters Patent, is-

A window-frame having its stiles provided with outside stops d,sash-guides in the form of strips each comprising two sections ofunequal length, the short section being rigid and the long sectionpivoted to the upper end of a frame-stile, and other sash-guides in theform of strips 0 each comprising two sections of unequal length, theshort section being rigid and the long section pivoted to the lower endof a frame-stile; the meeting ends of all said strip-sections being atsuch elevation as to require bringing of sash a greater distance thanfull length out of normal position before either pair of the movablesections can be swung on their pivots, it also requiring that run-uplower sash be swung out before rundown upper sash can be swung out forremoval.

In testimony that I claim the foregoing I have hereunto set my hand, atMilwaukee, in the county of Milwaukee and State of Wisconsin, in thepresence of two witnesses.

JACOB APPELL.
